DONALD Trump was at the centre of fresh outrage yesterday as he claimed that more British Muslims join ISIS than the armed forces.

Donald Trump claims more British Muslims join ISIS than the armed forces

The controversial 69-year-old US Republican presidential candidate also refused to back down in his ongoing verbal spat with British politicians.

Earlier this week he claimed that parts of London were so radicalised that police refused to enter. Scotland Yard refuted the claim but some officers later came forward to confirm their fears of terrorism.

Mr Trump has called for a ban on all Muslims entering the US in the wake of the San Benardino shooting massacre in southern California in which 14 people died at the hands of killers inspired by Islamic extremists.

Donald Trump's comments on Muslims have caused outrage across the world

In Scotland, meanwhile, First Minister Nicola Sturgeon stripped Mr Trump of his role as business ambassador, and Robert Gordon University revoked an honorary degree.

It sparked a furious reaction from Mr Trump.

The US presidential contender, who owns two major golf courses and plans to spend £200 million in the country, said: "I have done so much for Scotland. If they were going to do this, they should have informed me prior to my major investment."

Despite the controversy, Mr Trump was becoming increasingly popular with American voters.

Polls show his views are popular with the Republican primary electorate he is courting.

Bloomberg found that 64 per cent of likely Republican primary voters support the Muslim travel ban, compared to 35 per cent overall and 17 per cent among Democrats.

Critics accused Mr Trump of being 'racist', 'grotesque' and even 'more disgusting than Hitler'.

However other people said he was 'right' and described his claims about Isis and the British Army as 'scary.' As he faced worldwide condemnation for his incendiary remarks, Mr Trump said: "I am the least racist person you have ever met."

He said he was "calling for a total and complete shutdown of Muslims entering the United States until our country's representatives can figure out what is going on."

He then claimed that in Britain "we have places in London and other places that are so radicalised that police are afraid for their own lives."

After hearing that some serving police officers agreed with his claims, he said "Many police officers in London have come forward to confirm their fears of terrorism.

"I only said what needed to be said, and when I am elected no one will be tougher or smarter than me."

The billionaire said his comments had sent 'my poll numbers...through the roof' and admitted he could stand as an independent candidate.

Mr Trump also spoke in greater detail about his proposal to stop allowing Muslims into the US.

"I'm doing good for the Muslims."

He added: "Many Muslim friends of mine are in agreement with me. They say, 'Donald, you brought something up to the fore that is so brilliant and so fantastic.'"

He added that "one of the most important people in Middle East" thanked him for his plan.

Asked if he feared how his comments might impact his business dealings in the Middle East, he responded: "What I am doing right now is far more important than any business in the Middle East."
